Modern smartphones like the Xiaomi Redmi 8 have powerful functionality that is hidden from the default user, and many device owners are faced with the need to access hidden system settings to debug applications, install custom firmware or fine-tune the system performance, for which purpose the company’s engineers have provided a special section known as the developer menu.
Activating this partition on the MIUI shell requires a specific sequence of actions that may not seem obvious to a beginner. Unlike standard settings, this mode does not appear on the menu until you confirm your rights as an advanced user. In this article, we will discuss the activation process in detail, explain the assignment of key parameters and caution against potential risks.
Enabling hidden options opens access to system logs, allows you to manage interface animations and even emulate location. However, it is worth noting that incorrectly changing some parameters can lead to unstable operation of the Android operating system.
Why you need a developer mode on Redmi 8
The main purpose of the hidden menu is to provide tools for testing applications and debugging code by programmers, but ordinary users can find useful features here, for example, to speed up the interface or force the display to change the orientation of the screen. USB debugging allows you to transfer data between the computer and the phone at the deep system level, which is necessary for installing drivers or using console utilities.
It also allows you to control the speed of animations of windows and transitions, which visually makes the Redmi 8 smartphone faster and more responsive. Some users activate the mode to force the dark theme to be included in applications that do not officially support it, or to display the percentage of battery charge in the status bar in more detail.
Importantly, access to these settings gives you almost complete control over the behavior of the operating system. Changing the DPI (dot density) scale allows you to resize interface elements, making the font smaller or larger regardless of the standard screen settings, this is especially true for people with visual disabilities or those who are used to a certain scale of content display.
⚠️ Attention: A mindless change in the For Developers section may cause some applications to stop running and the system to start operating unstable.

Before changing any settings in the developer menu, take a screenshot of the original parameters values, which will quickly return everything as it was in the event of a failure.
Step-by-step activation of the hidden menu
The process of turning on the developer mode on Xiaomi Redmi 8 is standardized and takes no more than a minute. You will need to go to the basic settings of the smartphone and find the About section. This is where the button needed to unlock the additional features of the system is hidden.

- 🔐 Enter the screen unlock password if the system requests confirmation.
☑️ Activation checklist
Where to find settings after activation
After a series of clicks is successfully completed, the new section will not appear on the main settings screen, but will be hidden in the depth of the “Additional” menu, so that you do not overload the user interface with unnecessary options, you need to go back to the main settings screen and scroll down the list.
Find an item called “Additional” (or “Extended Settings” depending on the version of the MIUI translation) inside this section, usually at the bottom of the list, will be “Developers” and it indicates a successful activation of the mode.
Inside this menu, you'll find dozens of different options, grouped into categories: debugging, networking, input, drawing, and hardware acceleration. Searching through settings can make navigation much easier if you know the exact name of the feature you want.
| Parameter | Description of function | Recommended value |
|---|---|---|
| USB debugging | Allows debugging of the device when connected to the PC | Off (if not used) |
| Window animation | Speed of animation of opening applications | 0.5x or 1x |
| Keep the screen down. | The screen does not go out when charging | Off. |
| Limit of background processes | Limiting the number of working in the background of applications | Standard. |
It's worth noting that some parameters may be marked "Experimental," which are under development and may not work properly, and be careful when using them on the main device.
Configure debugging over USB and ADB
One of the most popular features for advanced users is debugging. USB. This option allows the computer to access the Android command line via the interface. ADB (This is necessary to install apps bypassing the store, remove full system logs or unlock the bootloader.
To work with ADB, you need to install the appropriate drivers and tools on your computer. Once you connect the Redmi 8 cable to your PC, you will see a request for debugging permission from that computer on your smartphone screen, you must confirm the action and optionally select "Always allow from this computer."
In some cases, especially when working with flashing tools (for example, Mi Flash Tool), you also need to turn off MIUI Optimization. This item is at the bottom of the developer menu.
⚠️ Attention: Disconnection MIUI Optimization can cause standard applications to crash, change fonts, and display the interface incorrectly.
You can also set up the default USB configuration in this section, allowing you to choose file transfer mode (MTP) or charging mode when you connect the cable, eliminating the constant choice of action in the notification curtain.
